ClipperCreek Power Sharing Product Lets You Turn One Charging Station Into Two

SEP 8 2016 BY JAY COLE 31

So you have bought an electric vehicle, and shortly thereafter added a dedicated Level 2/240V charging station to get “filled up” quick.  That’s great, but this isn’t 2011 anymore, now you are adding that 2nd plug-in vehicle to start your own personal armada of EVs, or perhaps even your workplace needs to add another station to squeeze everyone in.

ClipperCreek's Share2 EVSE system eases the difficulties associated with adding a 2nd charging station

ClipperCreek’s Share2 EVSE system eases the difficulties associated with adding a 2nd charging station for when your Model 3 arrives

Do you now upgrade your home or office’s power to service two EVs, and go through the hassle and cost to add another 240V circuit?

You could of course, but ClipperCreek has introduced another option  – something it calls Share2.

The way Share2 works is simple enough, as it allows any location to have 2 charge points without adding an additional 240V service.

ClipperCreek packages two of its Share2 enabled, HCS-40 charging units (32 Amp, 7.7 kW output) together allowing the L2 units to share one 40A circuit.

Once in operation, the station will offer full power (up to 7.7 kW) when only one of the EVSEs is in operation, and when a second connection is made to the other unit, power is automatically split in half (up to 3.8 kW) to charge both EVs at the same time.  Once one vehicle completes its charge, the other then gets ratcheted back up to full power.

Simple enough right?

Jason France, President/Founder of ClipperCreek talks about his company’s latest offering:

“ClipperCreek’s continuous and forward-thinking innovation efforts have resulted in another market value improvement, the Share2™. This enables customers to charge two vehicles at the same time, on one branch circuit, saving considerably on installation costs.

Electric vehicles are universally loved by our customers, who quickly discover they want a second plug in vehicle. Oftentimes their service panel cannot support the power requirement for an additional vehicle. Share2™ eliminates this obstacle.”

A bundle of two stations enabled with the Share2 technology (and with a 3 year warranty) is priced from $1498, and can be purchase here.

Fortunately, I had the “forward thinking” to put in 2 circuits when I added the first charger. 😉

When we built our house, we added a second 200 amp panel feeding 3 14-50 plugs. We also prewired for solar, adding in the exta disconnects, etc.

So much cheaper during construction than trying to retrofit.

I am super jealous I live in a house with 100 amp service and I have one model S and one Nissan leaf So as you can guess I have to redo almost all my electrical

Not necessarily, unless you want to.

I have only the original 1959 electric service the 2200 sq ft house was built with, and I have a large (8′ x 10′) hot tub, electric 3 person swedish sauna, 3kw ham radio station, 2 electric cars but I’m planning on 3, and central air conditioning for the whole thing. Plus a 3 horsepower 220 volt snowblower (homemade).

100 amps is ok for all this; but if a typical electrician went around adding up nameplates, he’d say I need at LEAST a 300 amp service.

You are correct sir.

But I would round that up to 400 amps:-! Well done on effective management of current flow and kWh consumption.

Haha, well, 400 amps is the maximum allowed for a residential rate service from any of the several utility companies in my area.

The thing I didn’t mention, is that with the exception of the Sauna, all heating appliances in my house (all eight of them), are natural gas. But apparently per the gas company I’m not using enough during the summer time since they refuse my meter readings, saying I couldn’t possibly be using so little gas. And I would need a much larger service without them. The Hot Tub was the hardest to convert, since although being large, I happened to pick the Brand that was the biggest Mechanic’s Nightmare (Dimension One). It still draws 25 amperes to run the 5 pumps.

If you are pulling permits for the car chargers you may be surprised to find that they require a service panel upgrade.
Car chargers are considered continuous duty loads. All of the others that you mentioned are intermittent duty loads.
I had to install two car chargers a L2 for a Leaf and a 50 AMP for their Model S. The building department mandated that the servuce be upgraded from a 200 AMP service to a 400 AMP service. That wasn’t required by me but by the building department.

Even more forward thinking would be a quad of hcs-60

It’s a good idea, but I wish Clipper Creek wouldn’t hog the electrical upgrade cash all for themselves… $1500 for 2x $600 EVSEs? C’mon…

tell that to the idiot who keeps plugging to the same station as yours even when there is an empty station. you end up paying the same but get half the charge or worst case end up going beyond the limited hours and have to pay an additional fine for over usage.

A relatively affordable alternative to the Wattzilla Duo I’d briefly considered when planning our new house. The desire to run one line, but have a multi-car EVSE appears to be rare, given how few offerings there are, outside of large, commercial units.

In the end, I went for an even more affordable option: reusing the Aerovironment EVSE which was a free perk when leasing my LEAF, and the L1 charger that came with my LEAF (upgraded to near L2, courtesy of evseupgrade).

We had to run two lines, which this EVSE avoids, but my total cost is far less than it would have been to run one line and pay $1,498 for the Share2. I realize this isn’t an option for everyone, and the target audience may be different; however, I would’ve jumped at the chance to go this route at ~$800 – $1,000. Half of that cost would’ve been recouped by selling the other two EVSE’s I have.

Nah. Putting in a faster Tesla Charger.

The funny thing about this story is that the two cars in the picture above can’t tell that they’re sharing one circuit. The Volt and the Spark only have 3.3kW on-board chargers, which is what, 14 amps?

My question is, if you have a Volt and an e-Golf charging with these Clipper Creek units, does the e-Golf get 15 amps (half) or does it get 16 amps (the remainder)? The new Tesla HPWC is smart enough to apportion the remainder when they are set up for load sharing.

Based off the description, sounds like it would be a straight 50/50 split if 2 EVs were plugged in. So if an i3 was charging, and then a PiP (with its 2.2 kW charge rate) plugged in, the max rates would be cut to 3.8 for both units. A rather dumb “smart charger”.

Hopefully I am wrong.

Hey bro,….

…..

…..

….it’s not 1999 anymore. And 2.2kW EVs are about to disappear.

According to the Share 2 Addendum for HCS Manual, on the Clipper Creek website, it will be split in half: “When both EVSE are charging vehicles, each EVSE will offer 50% of the circuit capacity to each vehicle (thus “sharing” the circuit breaker).”

So if you have two vehicles that can accept different rates, they’ll both take 3.8kWh if plugged in simultaneously.

So many of the comments have an extremely unrealistic assumption regarding how many kWhs a single household is likely to spend driving in one day. There’s only so much driving you can do, and even a short 8-hour night session with a ~7 kW charger will replenish you >50kWh.

Do the math. This thing is plenty enough for any normal household, even with 2 EVs.

In fact, for the vast majority of households it’s an overkill. If indeed we want to be forward-looking, then with a ~7kW charger, and a 2020s era household with two 150+ mile BEVs, you will likely need to to recharge each one only every other night. So you might as well remain with a single charger, alternate the charging nights, and save a good ~$1k of equipment.

But this seems a great solution for workplaces and EV fleets.

A+

Definitely seems this makes more sense for workplace/commercial use than residential. Especially knowing how expensive running wire in a parking lot can be.

Jeez! I was on board until I saw the price. You might as well put in two chargers at that point…

My thoughts exactly upon initial look. I guess it’s more geared towards those who don’t have an additional breaker to attach an extra EVSE (I’m in that boat). However, for $1500, I would probably get quotes to upgrade my panel instead (it would cost more, but it’s at least an upgrade to my home’s electrical versus just a set of EVSE’s).

This is essentially identical to the new CharePoint ‘TV-Set’ dual charger docking stations that they have in Irondequoit, NY next to the I-Square restaurant complex.

They have 2 – dual charge points (4 cars) running off or 2- 40 amp 200 volt circuits.

This was a NEW installation with Planned Throttling.

The reason? The state subsidizes everything, EXCEPT the owner has to pay the electricity, which means usage and demand charges.

Since 4 cars can only use on avg 1.5 kw each, the owner benefits, as this was obviously designed to use the least amount of juice possible since a 240 volt feed was only 1/10th the distance away.

err: 3 kw per car on average. This is the location for the “Drive ELectric” event next tuesday for Rochester, NY.

I just put in a sub-panel pro-actively on the initial install. I can put as many EV circuits from there as I want as long as they don’t exceed the panel capacity.

Tesla evse do load sharing out the box and at $500 each, all I need is a j1772 head to power my current ev’s until my model 3 shows up

I hope they can give an option to allow the first car charge at full power until it’s completed, then start charging the second car.

That is an excellent Product suggestion you might want to communicate directly to them – especially considering the rather higher price compared to just buying a 20 Amp unit and a 40 amp unit from them! But – if you actually can not install such an arrangement – this offer does have value! Their email – information@clippercreek.net

Also a good solution for apartment buildings and condos that have limited electrical supply without major transformer and panel upgrades

Related, my employer in central NY installed 8 EVSEs a couple years ago. Last year they added 6 more. This year they added 3 more to “fill” the row of spots with nothing but chargers.

It’s an impressive site in an area that is not adopting PEV’s at high rates.

Luckily my company is a bit of an anomaly, both in EVSEs and in plug-in owners… We have over a dozen PEV owners here and more to come.

it sounds a lot like the “hydra” which will work on any EVSE and split the power to 2 cars, (based on the openevse)

This is a good system if you have both cars inside or outside. I have a separate garage.
I have a charger outside and plan to add one in the garage.
This would help when I charge both my Leaf and Volt the same night. I would not have to go out and switch, when one is done.
I am installing a charger with a timer. That way I can set it to go off when I figure the one is done. I have from 7 P.M. to 7 A.M. to get the lowest rate, so plenty of time.
As I am in Ontario, Canada, word is the gov’t. plans to give us free charging, off peak, at night. With rebates up to 14 grand and free charging starting next year for 4 years, it is a great place to have an EV.
